Packet Tracer: Can only see 2 Gig interfaces when trying to plug in, but there are 3 Gig interfaces availible on the router

[kevpg138]

Hi, I'm trying to complete daily labs in packet tracer now that I've switched to online school. I'm want to have Router0 be connected to two other routers as well as a switch (3 devices), but only 2 Gig interfaces show up when trying to connect with a cable. 

If I hover over the device, it shows that there are 3 total Gig ports:

So my question is how do I fix this?

Hello,

post the zipped Packet Tracer project (.pkt) file with the two routers you have added here...

[Georg Pauwen]

Hello,

you need to use a 4331, not a 4321. I have added a 4331 with an additional interface to your project.

Thank you very much but unfortunately, I can not open the file and I don't have 4331 router in my Packet Tracer

I have 7.2.1 version of Packet Tracer

Hello,

I used 7.3.0. Higher versions can open lower versions, not vice versa. Can you install 7.3 ? The 4331 is the leftmost router icon...

[Sufi]

I have installed 7.3.1 now. 4331 has 3 GE which are by default interface., what if I need to add fourth one please

[Georg Pauwen]

Hello,

three is the maximum. To use to third one, you still have to add the GLC-T in the lower right slot.

[Sufi]

Thank you very for your help.

I know this is an old post but I had this problem recently and the easiest solution was to just select Router 2911 from the list and it showed all 3 interfaces needed without modification.  I hope this helps.

A solution was mentioned in the thread. three is the maximum. To use to third interface, you have to add the GLC-T in the lower right slot. This is non-intuitive, but worked for me with a little experimentation.

Good luck - Rich
